Migration of mouse 3T3 fibroblasts in response to a serum factor.

A serum factor that promotes migration of (mouse) 3T3 fibroblast cells is shown to be distinct from the growth-promoting and cell-survival factors of serum. The factor promotes migration of cells from the edge of a wound in confluent 3T3 cells, but cell migration under these conditions does not lead to the initiation of DNA synthesis. Subsequent addition of serum initiates DNA synthesis in the migrating cells. The results establish that breaking contacts between quiescent 3T3 cells is not sufficient to initiate DNA synthesis. The DNA synthesis observed in migrating 3T3 cells in the typical "woundhealing" experiment presumably results because the migrating cells have an increased ability to use serum factors. Serum-factor requirements for "wound healing" in cultured 3T3 cells are discussed.

Serum factor requirements of normal and simian virus 40-transformed 3T3 mouse fibroplasts.

Evidence is presented to show the presence in normal rat serum of four different serum factors essential for growth of 3T3 or SV40-transformed 3T3 mouse fibroblasts: a factor that specifically promotes growth of normal 3T3 cells; two factors that specifically promote growth of transformed 3T3 cells; and a factor that sustains viability of both normal and transformed 3T3 cells in serum-free medium, probably without inducing growth of the cells. These factors are separated and partially purified.
